Miracle Planet: Ep.4 – Extinction And Rebirth

Extinction And Rebirth documents the time about 250 million years ago, when all life nearly disappeared from planet Earth. Scientists now believe the cause was an eruption of the Earth’s molten core that triggered global climate change. The resulting drop in oxygen levels allowed dinosaurs to reign because of their respiratory systems. But in the Earth’s continuing cycle of Extinction and Rebirth, they too would suffer a catastrophic end some 150 million years later. The film then follows gargantuan creatures through life and death and chronicles the early rise of mammals as the next dominant creature on the planet.
